Choose the model required by the original LED cabinet design. Do not select a replacement by enclosure size or product family name alone.
Compatibility and installation notes
- Verify that the equipment requires both 4.2VDC and 3.2VDC outputs.
- Confirm total load, connector pinout, polarity, mounting dimensions, and airflow.
- Disconnect mains power before wiring or servicing the unit.
- Use protective grounding and keep ventilation paths unobstructed.
- Installation and testing should be completed by a qualified technician.
